To all whom it may comm-n Be it known that we, 01. G. HAL'S'URSl-JS, a citizeh of the I'Iiu dom of Nai wa y, residing at. (Thimgo, Coo county, Ilhnms, Fm: S. Honour? 5i citizen of the United States,

Jackson county Missouri, and EDGAR G. mums, a citizen the United States, residing at Oak 'Park,

.. Cook county, Illinois, have invented certain new and useful Improvements in Rumors, of which the following is a gpmificahipn, reference hiughad to the accompanying drawing.

Our invention relates to liquid fuel burnax s that am used in steam generators, and iu:-rmces., or for other heating pt n'posesmpd it, consists in the matters hereinafter (11S;-

ciosod-hmilmintad out in the appamied In the accomlpanying drawings, which ilhistmto one om mihmenz of our i.nvn tion, Figure 1 is a longitudinal central se ctlonnl om on tha line 1--1 of Fig. 2, with the motor in top plan; I

Fig-:2: is {Locational view on the line 22 -of.Fig. 1, with the hub of tho burner-head Fig. 5 is an onlarg'ed sectional viewof the imruor-haigd, and l Fig. 9 is u-t-ransverso sectional view on in the drawings, the raforouco nqmergl 10 represent: the burner-casing Wind! 18 suhstzmtiaiiy circular in cross-section and somewhat reduced in cross-sectional area at its rear or discharge and 11; it may be of any suitable construction, and in the form shown is composed of threi: sections suitai-y connoomd together by bolts passing throu h the flung-as 12 at their meeting ends. T e

air intake end of the casing is provided with a supportin base lacnn'ieti on the frame (not shown and having zm-air-iniet 1; at its lower portion communicatin with the outside air or a suit-able source 0 air-supply as desired, and the dischar e and of the easingis supported by suitab a brackets 15 on the frame. i

The, operating shaft 16 is centrally jourmiied in the humor-casing in suitable 0mlml-boxes l7 and 18 carried by bearingblocks 19 and 20, mspoctivoly, the former supported in one of the walls of the intn e and of the casing and the 1mm being an ported on the interior air-vanes 21 near a dischai end thereof. The shaft ext-ends beyond tie box 18 into and through on oil ohamben22 formed in the stationary hub 23 which is carried on the outer end of the box, this chamber beitig providad with in oil passage or duct 24 leading throw the hub 23 and block to an oil-pipe 5,

which is connected with a suitable soul-ca of oil-supply 26 of either the wolhknown gravity or force-feed ty e. The inner and of the box 18 is rovni ed with a smiling-box 27, which is (2 sad by a ghmd 28, to pro vent the oil leaking from chamber 22 back along the. shaft- The shaft 16 is connected to a motor 29 hy a suitable couplin 80 which ermits the fllllfii to move axia y as hereinafter described, and within the chamber 22 the shaft is reduced in diameter to provide a valve 31 which ooiiperates with a correspondingly shaped valve'seat 32 formed at the inner and of an oil passage in the partition 88 of the chamber 22, the passage in the partition being of eater diameter or crosssectional area' an the reciuced portion of the shaft to insure the free flow of an adeuate supply of oil to the harm-head when t a valve is unseated. The outer end of the hub 23 is roducad and rovideld with a. central bore through whic the reduced and of the shaft ireely passes, and also with suitable oil as 34 outside of and conontriowith this hora to form an annular hurneohead to whi the oil flows from the chamber 22 when i a; valve 31 ishnseated.

The reduced portion of the s f xtends beyond the burner head and carries at its end an oil atomizing and spray: cap of cup-shaped contour; the base o the cap is secured to the shaft end, and its body 86 extends over and incloses the reduced outer end of the hub 23 i md has an inwardly directed flange 37 at its inner end to close the space between it and the reduced and of the hub. The outer end of the cap is provided with a series of oil-orifices 88 cxtondin lat orally through its base 35 and ra ially through the contiguous portions of its body, whereby when the cap is revolved the 011 is atomized and sprayed out into the end of the casing 10 in a )lurality of lines or streams extending radially toward the surface of the casing and laterally toward its open end. The base of the cap IS provided on its exterior with a. conical head 39 which prevents any vortex or the formation of any eddies; the head 89 forms a convenient means of securing the cap to the shaft as its tail 40 may extend through the base of the cap and be fixed to the shaft as shown.

The shaft is incloscd between the blocks 19 and 20 by a housing composed of the front and rear sections 41 and 42, the former bcin carried by the block 19 and the latter by t 1e block 20, and thesections of the housing are spaced apart at their inner ends to provide space for the travel or movement of tho. interposed propeller 43 along the line of the shaft. The propeller is pinned to the shaft and has a central drum 44 of the same diameter as the hoasing but somewhat less in len th than the distance between the inner cm s of-the housing sections to permit the pro ellcr to move longitudinail of the line of t we shaft, the drum being 1 need at each and to make a telescopic fit with the sections of the housing so that the latter are closed in all positions of the propeller. The ournal-hox 17 at its inner end is shoulder and reduced. in diameter to receive a sliding sleeve 45 which has an out-tamed or radial flange 46 at its inner end and carries an expanding coiled s rin 47, which reacts between the shoal er- 0 the box 17 and the flange of the sleeve, and so tends to move the sleeve inwardly in the line of the shaft. The box 48 of a suitable ball-bearin is mounted in the shaft-housing, being fric 'onally held against rotation therein but adapted to move axially therein under the'stress of the flung of the spring-plowed sleeve 45, the balls of the bearing acting against a fin or collar 50 on the shaft 16, so that the normal stress of the spring 47 tends to move the shaft in its aid line to close the valve 31 in its seat, the shaft being men to have axial movement in its jo'izrnaloxes limited by box 17 and seat 32 to avoid the abutment of its'drum with the inner ends of the housing sections 41 and 42. The carnal-box 17 has threaded engagement wi its blook 19 so movement of the shaft. The box 52 abuts against the radial or out-turned flan e 53 of a sleeve 54, which is loosel can: on the shaft 16 and is surroun by a. coiled sprin 55, which reacts between the flange and t e end of the gland 28. The sleeve 54 is longer than its spring and extends into the gland, and the expansion of the spring 55 keeps the gland in place to close the stalling-box 27 when the shaft is moved by thwiropeller to unseat the valve 31.

hen the motor 29 is in operation and shaft 16 is revolved, the re eller 43 retracts the shaft axially toward t o intake-end of the casin overcoming the resistance of the spring 4 and withdrawing the valve 81 from its seat, so that the 011 freely passes from the chamber 22 to the burner-head where it is sprayed out radially and forward] tower the mouth of the casing; the rope lcr 43 also acts as a. fan or blower to raw the air for combustion of the oil into the casing throu h its air-inlet 14 and force it forward to tie flame zone. .When the motor stops ill'ld the propeller ceases to re valve, the spring 47 expands and protracts the shaft axially to seat the valve 31 on its seat 32 to stop the passage of the oil to the burner. In both positions of thcshaft the spring 55 holds the gland 28 in position in the stalling-box 27, and as this s rin is relatively weaker than the spring 4? it does not interfere with the protractin action of the latter to seat the valve 81. he sleeves 45 and 54 do not revolve, so each prevents any torque in its spring; and the springs have merely a pushing action.

A suitable spark-plug 56 is carried on one of the vanes 21 in proximity to tipburnerhcad, and is included in an ignition circuit In any suitable manner, to ignite the fuel formed byl the mixture'of air and atomized oil. In t e present form the circuit of the spark-plug is completed thronih the parts 011a voluminous body of atomized Oil of 4.
